tmp=[]forcins:tmp.append(bin(ord(c)).replace('0b','')) 1. 2. 3. 七. Python chr() 函数 chr() 用一个范围在 range(256)内的(就是0～255)整数作参数,返回一个对应的字符。 返回值是当前整数对应的 ASCII 字符。 例如 >>>print chr(0x30), chr(0x31), chr(0x61) # 十六进制 0 1 ...
在Python2中,range()与xrange()功能是一样的,多用于for循环。但是不同的是range产生的是一个list对象,而xrange是一个生成器对象。从性能上,xrange优于range。 因此要生成很大的数字序列的时候,用xrange会比range性能优很多,因为不需要一上来就开辟一块很大的内存空间。 在python3中xrange()已经不存在了,range()...

That is, the value range [0,255*256] is mapped to [0,255]. . - If the image is 32-bit or 64-bit floating-point, the pixel values are multiplied by 255. That is, the . value range [0,1] is mapped to [0,255]. 所有像素都乘以 255,然后越界的在 255 处截断,因此显示大面积白色...
